"Yes, I myself heard at the corporate level in the course of fierce debate that someone was saying there: "But we'll stop the transit at all". I'm not sure that it should be done - the cessation of transit through Ukraine," he said.
Putin stressed that the issue of further cooperation between Russia and Ukraine in terms of transit of Russian gas to Europe depended on whether Ukraine would bring its gas transportation system management standards in line with European requirements.
"Everyone demands that the Nord Stream in general and the Nord Stream II in particular meet certain requirements in the future. These requirements are reliability, market-oriented operation of the gas transmission system, legal and administrative control in accordance with the highest standards. Our Ukrainian partners are capable of doing the same things we do together with our European partners on the Nord Stream II. If they turn out to be capable - we will continue working with them, if not - well, we'll see how to deal with it then," Putin said.
